Trade: Which company has the second-best Coding AI model end of May?
Resolution criteria on PolyGram: This market will resolve according to the company that owns the model that has the second-highest arena rank based on the Chatbot Arena LLM Leaderboard (https://lmarena.ai/) when the table under the "Leaderboard" tab for "Coding" is checked on May 31, 2026, 12:00 PM ET. Results from the "Rank" column under the "Text Arena | Coding" Leaderboard tab at https://arena.ai/leaderboard/text/coding-no-style-control with style control off will be used to resolve this market. Models will be ordered primarily by their leaderboard rank at the market’s check time.

Market context
The Chatbot Arena Coding Leaderboard will determine which company owns the model ranked second-best for code generation tasks on 31 May 2026. The settlement relies on the specific "Text Arena | Coding" rankings published at arena.ai, with ties broken by the leaderboard's stated methodology. Current order book pricing reflects an 88% probability that a particular company will hold this position at the settlement window.
Historical leaderboard volatility provides context for interpreting this high implied probability. The Coding Arena rankings have shifted substantially over the past eighteen months as OpenAI, Anthropic, Google, and others released successive model versions. Second-place positions have rotated between Claude variants, GPT models, and Gemini releases as each company deployed improvements. The 88% figure suggests traders view one company as heavily favoured to retain or reclaim the second-ranking spot, though the specific identity of that company is not disclosed in this market framing.
Traders should monitor several catalysts through May 2026. Major model releases or fine-tuning announcements from leading labs could reshuffle rankings substantially; Anthropic, OpenAI, and Google have historically announced significant updates on irregular schedules. The Arena's evaluation methodology itself occasionally undergoes refinement, which could affect how models are ranked. Additionally, the leaderboard's user voting patterns—which drive the underlying Elo ratings—may shift if the coding community's preferences change or if particular use cases gain prominence. Tracking pre-May announcements and benchmark releases will be essential for assessing whether the current crowd probability remains well-calibrated.

How this market resolves
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
How to trade this market step by step
The mechanics for trading "Which company has the second-best Coding AI model end of May?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
- Sign in on polygram.ink with your email — no full KYC under $1,500 lifetime trading volume.
- Deposit USDC on Polygon (lowest fees, ~$0.01 per transaction) or Ethereum. Funds credit after 12 confirmations.
- Pick a side. Buy YES if you believe the event will happen; buy NO if you think it won't. The current YES price reflects the market's collective probability.
- Size your position. If you stake 100 USDC at 50% YES, you'll receive shares that pay $200 if YES resolves true — a 100% gross return. If NO resolves, your shares are worth $0.
- Set risk controls (optional). Stop-loss, take-profit, and limit-order types all supported. Use the trade ticket's slippage box to cap your maximum entry price.
- Wait for resolution. When the event resolves on-chain via the UMA optimistic oracle, the winning side settles to 100¢ automatically and USDC hits your balance within seconds. Withdrawable to any wallet you control.
How active is this market?
$5K in lifetime turnover and $7K of resting liquidity puts this market in the below the median by volume for rewards 20 4pt5 50 contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
Last 24 hours alone saw $46 in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for under a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Key terms
- YES / NO share
- A binary outcome token that pays $1.00 if the underlying claim resolves true (YES) or false (NO), and $0 otherwise. The market price between 0¢ and 100¢ is the implied probability.
- CLOB
- Central limit order book. The matching engine that pairs YES buyers with NO buyers (effectively the same trade). Polymarket's CLOB on Polygon executes trades on-chain via the conditional-tokens framework.
- Liquidity
- USDC capital sitting in resting limit orders inside the order book. Deeper liquidity means smaller slippage on large trades and a tighter bid-ask spread.
- UMA optimistic oracle
- The on-chain dispute system that settles each Polymarket market. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution.
- Slippage
- The difference between the displayed mid-price and your fill price. Affects market orders most; limit orders avoid slippage but may take time to fill.
- Conditional token
- ERC-1155 outcome share issued by Gnosis Conditional Tokens on Polygon. The token type that resolves to $1.00 or $0.00 at settlement.

Risk and regulatory note
Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
